ABSTRACT:
A pipe fitting assembly is provided for an intake manifold defining a generally cylindrical bore and having at least one tab portion defining at least one groove. The pipe fitting assembly includes a fitting member having a generally cylindrical portion configured for insertion into the bore such that the fitting member is rotatable between a first and second position. At least one flange is formed on the fitting member and is operable to engage the at least one groove when the fitting member is rotated from the first position to the second position, thereby preventing the removal of the cylindrical portion from the bore. A tube member is also provided having a first end mounted with respect to the fitting member and a second end mounted with respect to the intake manifold. The tube member is operable to retain the fitting member in the second position.
